Hotel Occupancy

C++ Only

Program Description

Write a program that calculates the occupancy rate for a hotel. The program should read its data from a file named "hotel.dat". The first line of this file will be a single integer specifying the number of floors in the hotel. Each of the remaining (N) lines will have two integers; the number of rooms on that floor and the number of occupied rooms on that floor.

Your program should display the following:

• How many rooms the hotel has,
• How many rooms are occupied,
• How many are unoccupied, and
• The percentage of rooms that are occupied.

Notes

1. Your program should be named hotel.cc.
2. You can build this program initially to read from the keyboard, get that working, and then modify the program to read from the file.
3. You will need to create the "hotel.dat" data file.

Write a JAVA application that asks elementary students a set of 10 math problems

50. First ask the user for a level and a problem type.
50. You need to validate the level and problem type and loop until the user enters a correct one.
50. There should be 3 levels. Level 1 operands would have values in the range of 0-9, level 2 operands would have values in the range of 0-99, and level 3 operands would have values in the range of 0-999.
50. Each problem will consist of three randomly generated operands.
50. There should be 4 problem types. Problem type 1 requires the student to find the sum of the three numbers, problem type 2 requires the user to find the integer average of the three numbers, problem type 3 requires the user to find the largest of the three numbers, and problem type 4 requires the user to find the smallest of the three numbers.
50. The program should ask the user 10 questions.
50. The program should randomly generate the numbers for each problem and display them to the user. Then the program should get the users answer and check that answer.
50. The program should provide individual feedback for each problem. There should be 3 different positive and 3 different negative feedbacks chosen from for each problem.
50. After the user finishes their 10 problems, display the number they got right and then query them if they want to play again. If they choose to play again, get a new level and problem type before asking 10 new problems.

Maximum value and its index in an array

java program that:

• Receive as input in command line the size of an array (n)
• Generate an array with numbers between 1 and 100 (inclusive 1 and 100) with the given size (a)
• Print the array with the format: {a, b, c, ..., x}, for instance {1, 2}
• Compute and print in the console the following:
  • maximum value in the array
  • one index on which the maximum value appears (a number from 0 to n-1)

Use the well-ordering property to prove the division algorithm. Recall that the division algorithm states that if a is an integer and d is a positive integer, then there are unique integers q and r with 0 ≤ r < d and a = dq + r.

Q1. What are the three main types for formal verification and can you give names for industry tools in formal verification?

Q2. Why IoT verification is not easy?

Calculate interest on balances up to 30,000( 3.25% interest) and above 30,000(.25% interest). In this program, we prompt the user for the balance and output the dividends earned. (example a 10,000 deposit earning 1.15% would earn 10,000*1.15%=$115)

In this program we prompt the user for the anticipated balance and then output the dividends earned.

What formula would you create if you prompt the user for the balance and then display dividends earned?(you can use variable constants, if then statements.

JAVA

In the last lesson, we wrote a class with methods to print out the song The Ants Go Marching. Notice that this is a class where there are no instance variables and we don’t really need to generate multiple objects. With students or pets, it makes sense to have multiple objects. With the Song, we can just make the methods static and have just 1 copy of them.

1. Copy in your class from the last lesson into this active code window. Change the method(s) that print out the verses of the Song to be static. In the main method, change how you call the static methods by using just the classname instead of creating an object.

2. Add a static variable to the class that keeps track of the number of verses. Increment this variable in the method verse and print it out at the beginning of the verse.

public class Song
{
// Add a static verse counter variable

// Change the method(s) to be static

public static void main(String args[])
{
// Call the static method(s) to print out the Song

}
}

Computer Science

Design and implement an ADT that represents a triangle. The data for the ADT should include the three sides of the triangle but could also include the triangle's three angles. The data should be in the private section of the class that implements the ADT.

Include at least two initialization operations; one that provides default values for the ADT's data, and another that sets this data to client-supplied values. These operations are the class's constructors. The ADT also should include operations that look at the values of the ADT'S data; change the values of the ADT'S data; compute the triangle's area; and determine whether the triangle is a right triangle, an equilateral triangle, or an isosceles triangle.

Code must be written in C++ thanks.
